Adamantium is stronger than Vibrainum in the comics, and unsure about the movies. Vibranium disperses damage from kinetic energy into vibrations.

But how was it mined and been able to break down to be converted to other things like ships, shields, body armor?

Vibranium is mined using sonic technologies. Unsure about how it is forged.

Is that in the Comic or Marvel Universe?

Comic as you are asking in the comic book community.

It isn't the hardest, it has a special property which allows it to absorb, store, and release kinetic energy.

So if you hit it with a hammer, that's not going to do much, but there are other forms of harvesting and molding it that don't involve kinetic energy.
